Click for Vacation Video

Welcome to Spintronic Computing. Spintronic computing, also known as magnetoelectronics, is an emerging technology that exploits the intrinsic spin of the electron  and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices. It is tied closely to quantum computing – a quantum computer is a device for computation  that makes direct use of quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data. Both practical and theoretical research continues with interest, and many national government and military funding agencies support quantum computing research to develop quantum computers  for both civilian and national security purposes.

Frbiz.com reports International Quantum computer research Breakthrough

Reporter on the 29th learned from the China University of Technology, the school Microscale Science Professor Du Jiangfeng National Laboratory research team led by the Chinese University of Hong Kong Professor Liu Renbao cooperation, through electron spin resonance experimental technique for the first time in the international community through the solid-state system Experimental realization of optimal dynamic decoupling, making the advent of quantum computers possible.

It is reported that the combination of quantum mechanics and computer science and quantum computing is a big dream of mankind. The nature of quantum computing is the use of quantum coherence, but in reality due to the environment will inevitably interfere with the quantum system, coupling occurs, so that quantum coherence decay over time, decoherence occurs, computing tasks can not be completed. Therefore, to make quantum computing a reality, the first urgent problem is to overcome decoherence.

Professor Du Jiangfeng said that in order to break down the natural integer 500, for example, is currently the fastest computer will need a few billions of years to complete, while the quantum computer, the same repetition frequency, one minute can be resolved. However, quantum computing, as human beings take some time to think. The length of time depends on the quantum coherence, coherence to maintain the longer quantum computer can handle the complexity of the higher, more difficult information. Therefore, improving the quantum coherence, to enhance the ability of quantum computers is essential.

In order to maintain quantum coherence, a physicist for the very many ways in which the optimal dynamic decoupling is the most effective methods. Professor Du Jiangfeng said that the optimal dynamic decoupling method is carefully designed by a bunch of microwave pulses directly on spin electronics, spin electronics repeatedly to flip, “feel” to the outside down and turned over to eliminate electron spin and the environment in the nuclear spin coupling between the protection of the quantum coherence electron spin.

After years of efforts, Du Jiang-Feng research team has successfully established the only China can simultaneously manipulate electron and nuclear spin of the experimental platform. The researchers used a maximum of seven microwave pulses into a material called malonate where the electronic spin coherence time to be extended from less than 1/20000000 seconds to nearly 1/30000 seconds, this time has been able to meet a number of quantum computing tasks. Research shows that even at room temperature, such programs also can work, which developed for the use of solid materials can be used at room temperature, laid the foundation for quantum computers.

The researchers believe that once the real-solid system, the various decoherence mechanisms are fully understood by people, high-precision coherent control will be easier away from the true realization of quantum computers are no longer distant.

It is learned that the results published on October 29 published an authoritative international magazine “Nature” on. Reviewers that “the working effectively maintained a solid-state spin quantum coherence bits of solid-state spin quantum computing truly has a great significance.”

The Next Generation Of Computers Is Quantum Computers.

Taking the Quantum Leap

While it may seem that the evolution of computers is about at its end, that is not the case. The next generation of computers is quantum computers.

The reason behind continuing computer evolution is the continuing thirst we have for speed and capacity of our computers. Way back in 1947 an engineer and computing expert, Howard Aiken, predicted that all the United States need to satisfy its need for computers were six digital electronic computers. Other scientists and engineers that followed Aiken added to the volume they predicted as being adequately massive, but were also far too conservative.

What none were able to predict that scientific research would produce voluminous quantities of knowledge that needed to be computed and stored, nor did they predict the popularity of personal computers, and the existence of the Internet. In fact, it’s hard to predict if humankind will ever be satisfied with its computer power and volume.

A basic computer premise, called Moore’s Law, says that the number of a microprocessor’s transistors doubles every 18 months and will continue to do so. What this means is that by no later than 2030 the number of microprocessor circuits found in computers will be astronomically high. This will lead to the creation of quantum computers, whose design will use the power of molecules and atoms for processing and memory tasks. Quantum computers should be able to perform specific calculations billions of times more quickly than can the current computers that are based on silicon.

Quantum computers do exist today, though few and they’re all in the hands of scientists and scientific organizations. They are not for practical and common use – that is still many years away. The theory of quantum computers was developed in 1981 by Paul Benioff, a physicist with the Argonne National Laboratory. Benioff theorized going beyond the Turing Theory to a Turing machine with quantum capabilities.

Alan Turing created the Turing machine around 1935. This machine was made up of a tape whose length was unlimited and which he divided into small squares. Each square either held the symbol one or the symbol zero, or no symbol at all. He then created a reading-writing device that could read these zero and one symbols, which in turn gave these machines – the early computers – the instructions that initiated specific programs.

Benioff took this to the quantum level, saying that the reading-writing head and the tape would both exist in a quantum state. What this would mean is that those tape symbols one or zero could exist in a superposition that could be one and zero at the same time, or somewhere in between. Because of this the quantum Turing machine, in contrast to the standard Turing machine, could perform several calculations at once.

The standard Turing machine concept is what runs today’s silicon-based computers. In contrast, quantum computers encode computer information as quantum bits, called qubits. These qubits actually represent atoms that work together to act as a processor and as the computer’s memory. This ability to run multiple computations at one, and to contain several states at the same time, is what gives quantum computers the potential to be millions of times as powerful as today’s best supercomputers.

Quantum computers that have 30 qubits would, for example, have processing power equal to today’s computers that run at a speed of 10 teraflops (trillions of operations per second.) To put this in perspective, the typical computer of today runs at gigaflop speeds (billions of operations per second.

As our cry for more speed and more power from our computers continues, quantum computers are predicted to be a readily available product sometime in the not so distant future.
